Having completed observations at 2.10, steered 300 degrees along the foot of a range of trap hills; at 3.50 passed a dry salt lake on our right, and at 5.15 bivouacked on the side of a trap hill, among some fine oat-grass growing on calcareous tufa.

Calcareous Spars, Shells converted into a kind of Agate, corallines in Marble, ores of Lead, Copper, and Zinc, and many strata of Flint, or Chert, and of Toadstone, or Lava, abound in this part of the country.

calcáreo, -a, calcareous.

It is a beautiful but uncommon shrub, and succeeds very well in chalky or calcareous soil.

If blowing off be sufficiently practised, the scale upon the flues will never be much thicker than a sheet of writing paper, and no excuse should be accepted from engineers for permitting a boiler to be damaged by the accumulation of calcareous deposit.

The upper coal formation occupies three-fifths of the State, commencing at 41° 12' North latitude, where, as also along the Mississippi, whose banks it touches between the places of its junction with the Illinois and Missouri rivers, it is enclosed by a narrow layer of calcareous coal.

This terre bleue, as the peasants call it, was not the only sign of a change in the formation; fragments of calcareous stone were mixed with the brown soil.

Here the lower formation was schistous, the upper calcareous.

I was on the border of the Causse de Larzac, one of the highest, most extensive, and hopelessly barren of the calcareous deserts which separate the rivers in this part of France.

Before the cheese became an important article of commerce these were natural caverns, such as are everywhere to be found in this calcareous formation, but now they are really cellars which have been excavated to such a depth in the rock that they are to be seen in as many as five stages, where long rows of cheeses are stacked one over the other.

Chalk produces champagne, and some of the best wines of Southern France are grown upon calcareous soils where the eye perceives nothing but stones.

I now drank the fragrant light wine of the Gévaudanthe calcareous district of the Upper Tarnwith a pleasure not unmixed with sorrow; for the phylloxera had found its way up the gorge, and the vineyards were already sick unto death.

All these calcareous rocks are breaking up.

The fountain would be remarkable in another region by the volume of water that gushes in all seasons like a little river out of the earth; but there are so many such between the Dordogne and the Tarn, wherever the calcareous formation has lent itself to the honeycombing action of water, that this copious outflow loses thereby much of its claim to distinction.

And these prodigious slabs of gneiss now lay amidst schistous marl and calcareous rock.

There is not an atom of calcareous stone in the whole country: almost all the plants are twisted and thorny.

On an arenaceo-calcareous substance, etc. Quarterly Journal Royal Institution October 1823 volume 16 page 79 to 83.)

PISONIA ISLAND, on the east of Mornington's Island, is composed of calcareous breccia and pudding-stone, which consist of a sandy calcareous cement, including water-worn portions of reddish ferruginous matter, with fragments of shells.

Calcareous incrustations, including fragments of madrepores, and of shells, cemented by splintery carbonate of lime.

The specimens of the rocks in its vicinity are, dark grey granite, somewhat approaching to gneiss, with a few specks of garnet; and a calcareous, probably concretional stone, enclosing the remains of shells, with cavities lined with crystals of calcareous spar.

A large rounded pebble, consisting of ferruginous granular quartz, of a dark purplish-brown colour, and considerable density, was found here; near a fireplace of the natives, by whom it is used for making their hatchets; with a fragment of a calcareous incrustation, like that of the west coast hereafter mentioned.

Indistinct specimens containing numerous fragments of shells, in a calcareous cement; the substance of these shells has at first sight the appearance of chalcedony, and is harder than ordinary carbonate of lime.

Two varieties of a calcareous rock, of the same nature with that of Dirk Hartog's Island; consisting of particles of translucent quartzose sand, united by a cement of yellowish or cream-coloured carbonate of lime, which has a flat conchoidal and splintery fracture, and is so hard as to yield with difficulty to the knife.

Recent calcareous breccia.
